Integrated photonic circuits, increasingly based on silicon (-nitride), are at the core of the next generation of low-cost, energy efficient optical devices ranging from on-chip interconnects to biosensors. One of the main bottlenecks in developing such components is that of implementing diverse functionalities on the passive platform, such as light emission and amplification. A promising route is that of hybridization, where a new photonic material is combined with the existing framework to provide a desired functionality. Colloidal nanomaterials are perfectly suited for this purpose as they combine low cost synthesis and deposition with the ability to emit an amplify light over a broad spectral range. In this contribution, we highlight the role two-dimensional nanomaterials in this unique hybrid approach. Through use of quantitative and combinatory ultrafast spectroscopy, we reveal the peculiar photo-physics of this new class of solution processable nanoscale materials and show their potential for realizing low cost, small footprint integrated lasers.
